STOLPERSTEINE ('stumble stones')

"The artist Gunter Demnig reminds us of the victims of the Nazi-dictatorship by placing small brass memorial stones in the sidewalk in front of their last self-chosen residence. Until the end of 2006 he has laid about 9000 stones in more than 190 towns. "A man is only forgotten when his name has been forgotten", says Gunter Demnig. The stones in front of the houses keep the remembrance alive of those people who once lived here. On the stones it is written: HIER WOHNTE... HERE LIVED... A stone. A name. A human being. For 95 Euros you can adopt the production and lay of a STOLPERSTEIN."
